The purpose of the study was to experimentally model summation in convergent multiple control over selection-based verbal behavior. Eight undergraduate students participated. In divergent--convergent tact training, a three-choice match-to-sample task was used to establish two selection-based tacts for each of five pictorial stimuli. One textual…

A common distinction in engineering problems is classifying them as well-structured or ill-structured. It is assumed that classroom problems are well-structured while workplace problems are ill-structured. However, we cannot find empirical data to confirm or deny the claim that the bulk of classroom problems are well-structured. This research…

Attending to and tacting stimuli in a situation may facilitate recall of that situation. To evaluate this, we showed varied slide decks of 25 black-and-white stick figures engaged in actions to four adolescents and one child with autism. Ten minutes later, we asked them to name the pictures they remembered. Using a multielement design, we compared…

Background: Little is known about the categorization ability of children with intellectual disabilities (ID) in China, which is critical in guiding teaching practice and learning support strategies for those students. The study has aimed to explore the characteristics of categorization ability of children with ID. Method: This study used an…

This study examined the types of representations that primary school children create in solving different types of problems, the relationship between these types of representations, and the accuracy rates in solving the problems. The study was conducted with 80 students attending primary school's 2nd and 3rd grades. An achievement test prepared by…

We sought to evaluate a set of procedures based on Relational Frame Theory in teaching children with disabilities to reason analogically using relations between the contextual cues "same," "opposite," and "different." Two children were first taught to respond to the relational cues using common pictures and were…

Humans appear to intuitively grasp definitions foundational to formal geometry, like definitions that describe points as infinitely small and lines as infinitely long. Nevertheless, previous studies exploring human's intuitive natural geometry have consistently focused on geometric principles in planar Euclidean contexts and thus may not…

How does one assess developmental change when the measures themselves change with development? Most developmental studies of word learning use either looking (infants) or pointing (preschoolers and older). With little empirical evidence of the relationship between the two measures, developmental change is difficult to assess. This paper analyzes…

Early reading materials are replete with pictures. Pictures purportedly improve reading comprehension and motivation; however, the simultaneous presentation of pictures and text can also impede textual control for some readers. Attempts to remediate restricted stimulus control in picture-text compounds suggest that omitting the picture element is…

This longitudinal study examined how receptive and expressive vocabulary assessments capture vocabulary development in children with Autism Spectrum Disorder (ASD) and typically developing (TD) children. Using mixed regression modelling, we explored when children with ASD significantly different from TD children. We also examined the variability…

This study investigated the perceived funniness of misfortune in children and adults, examining the role of the misfortune victims' facial expressions. Participants included 100 psychology undergraduates and 97 4- to 5-year-olds from a middle-European country. Participants were presented with pictures in which misfortune victims exhibited either…

Phonological processing is an important contributor to decoding and spelling difficulties, but it does not fully explain word reading outcomes for all children. As orthographic knowledge is acquired, it influences phonological processing in typical readers. In the present study, we examined whether orthography affects phonological processing…

This study traced different types of distractor effects in the picture-word interference (PWI) task across repeated naming. Starting point was a PWI study by Kurtz et al. (2018). It reported that naming a picture (e.g., of a duck) was slowed down by a distractor word phonologically related to an alternative picture name from a different taxonomic…

Background: Although most prevalent in childhood, the acquisition of new words in oral vocabulary takes place right across the lifespan. Of the many factors that influence oral vocabulary learning, one extrinsic factor is the listening environment. The current study aimed to examine whether the presence of noise impacts oral vocabulary learning in…

Introduction: Analysis of the relationship between test scores and other variables provides an important source of evidence for validity. As a new instrument, evidence of validity of Pictorial Vocational Interest Inventory (PVII) is needed to support its psychometric properties. The purpose of this study is to obtain evidence of the validity of…
